Solution Overview
Problem
Existing electronic component conveyance devices experience jamming issues when conveying multilayer ceramic capacitors at high speeds due to misalignment of internal electrodes, leading to mechanical strength and acoustic noise variations.
Innovation Solution
The electronic component conveyance device incorporates a conveyance path with varying sidewall intervals and magnetic force generation units to align the electronic components' internal electrodes, ensuring the length direction of the components remains parallel to the conveyance direction, preventing jamming by using a first magnetic force generation unit to align and a second unit to facilitate rotation and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic component is conveyed at high speed through the rotation path, then productivity is improved, but the orientation of the electronic component becomes tilted causing jamming
Solution Approach 1:
The conveyance path dynamically changes the interval between sidewalls along the conveyance direction. The interval is larger in the midstream part and smaller in the upstream and downstream parts, creating a dynamic spatial constraint that guides the component through rotation while maintaining proper orientation at high speeds
Solution Approach 2:
The physical parameter of the conveyance path (sidewall interval) is changed along the conveyance direction. By varying the interval P2 in the midstream part to be larger than intervals P1 and P3, the system creates optimal conditions for component rotation and orientation maintenance during high-speed conveyance
2Reliability
If the sidewall interval is reduced to prevent jamming, then reliability is improved, but the component cannot rotate properly to align internal electrodes
Solution Approach 1:
The conveyance path is segmented into three distinct parts (upstream, midstream, downstream) with different sidewall intervals. This segmentation allows the component to experience different spatial constraints at different stages: larger interval in midstream for rotation, smaller intervals at ends for alignment and jamming prevention
Solution Approach 2:
The conveyance path is designed to perform preliminary alignment actions by constraining the component between sidewalls with varying intervals. The larger midstream interval allows the component to rotate into the correct orientation before entering the downstream section, ensuring proper internal electrode alignment
